CARTON-FILLING DEVICE.

Application filed peeember This invention relates tocarton filling devices and more particularly to a novel and improved means for filling a carton with a plastic or semi-plastic food or composition of matter such as described in my Patent No. 1,537,385.

One of the objects of my invention is to provide a carton filling device in which a container such as a collapsible or substantially rigid carton is plunged into a plastic or semi-plastic mass and completely filled in one operation, said filled carton being inverted and removed from the device whereby it may be closed or sealed.

Another object of my invention is to pro vide a carton filling device open at its top and bottom to receive either a polygonal or cylindrical carton in an inverted position whereby it may be forced into a plastic or semi-plastic mass completely filling the said carton and then removed from the top of the device to be closed or sealed;

Another object of my invention is to provide a carton fillingdevice of the character of the type above specified, embodying a novel and improved flat, platform which closes the open top of the device in one position and releasable to another position to support the filled container preliminary to its removal and sealing.

With the above objects in view and others which will readily su gest themselves, drawings depicting a preferred form of the invention are annexed hereto wherein- Fig. 1 is a perspective view, a portion of the bottom being broken away to show the knife edge and bottom support for an in-' verted container.

Fig. 2 is a similar view showing a cylindrical type carton filhng device.

Fig. 3 is a detail showing the guiding means for the sliding platform.

' Referring now to the drawings wherein like reference characters designate correponding parts throughout theseveral views, 5 designates the front or rear wall and 6 the sides of a olygonal shaped container, open at its top and bottom 8. Onthe inner surface of the walls and sides, I provide a ledge 9 .slightly above the bottom knife edge 10 to support the inverted polygonal container 11 which is inserted 'within the container with its closure flaps bent back. The height of the said container is slightly greater than the height of the carton, the closed bottom extending to the edge of the 8, 1925. ,Serial No. 73,984.

open top for a purpose 1presently to appear.

Rising vertically of t e container, I provide a frame consisting of rigid, parallel sides 12, 13, the lower ends 14 of which are bent inwardly flush, with the outer walls of .the container and permanently secured thereto as by soldering, riveting or an equivalent manner. The portion of the frame above the open top of the container is of a height somewhat greater than the height of the carton so that the latter may be easily and conveniently removed when filled as the entire device is inverted from the position shown by Fig. 1.

The sides of the frame are connected at the top by a cross bar which braces the same. said bar 15 being preferably rigidly attached at its ends in any suitable mechanical manner. Passing through the bar, there is provided a plunger rod 16 which carries a platform or plate 17 at its lower end, said plate being adapted to completely close the open top of the container when the carton is positioned to be filled. The platform or plate also retains the carton in an immovable position when forced into the plastic or semiplastio mass.

The ends of the platform or plate are provided with pins or lugs 18 bent upwardly and extending slightly beyond the edges thereof being adapted to operate and slide in the inner grooves 19 of the frame above referred to. If so desired the platform or plate may be made integral with a lug or extension to operate in the said guides for the same purpose. An operating handle 20 connected to the upper end of the plunger rod permits the latform to be raised or lowered in the o vious manner.

In the form of the invention shown by Fig. 2, a cylindrical container 21 is shown having a peripheral knife edge 22 and ledge 23 on which the bottom of the inverted'carton 24 may be positioned. The top of this type container is also open and the diameter is slightly greater than the diameter of-the carton employed. The sides of the frame however are bentslightly outwardlythe top edge of the container as indicated by'numeral- 25 to permit the free outward movement of the carton on the platform. The cylindrical platform or plate 26 operates in the same manner as that shown and described in connection with Fig. 1.

From the above description it will be read ily understood that in filling a carton with a plastic or semi-plastic mass, the carton with its open top is inserted within the container so that it rests onthe ledge adjacent the bottom. The plunger rod and its platform or plate are then moved to close the open top of the container to prevent the carton from moving or shifting. When thus positionedand plunged or forced into a plastic or semiplast1c mass, the carton may be filled completely in'one operation. After the container scribed comprlsing a container open at its top and bottom for receiving a carton in an inverted position, an open frame attached-- to and extending above the said container, a slidable plate or platform in said frame constituting a closure for the top of the container in one position and a seat for a filled carton in a second position, said plate or platform being movable toward one end of the frame whereby said filled carton may be removed through the said open top.

2. A carton filling device of the'class described comprising a polygonal container open at its top and bottom for'receiving a carton in an inverted position, the bottom of the container having a knife edge for penetrating a plastic mass, an open frame attached to the sides of the container and extending vabove the open top and a plate or platform constituting a seat for a filled container in one position and a closure for the open to of the container in a second position, sald plate being movable toward one end of the frame by the weight of a filled container thereon when the device is inverted whereby the filled carton may be removed through the said open top.

3. A carton filling device of the class described comprising a polygonal container open at its top and bottom for recelving a carton in an inverted position, the bottom of the container having a rectangular knife edge for penetrating a plastic mass, a ledge formed on the inner walls of the container adjacent the bottom, a frame attached to the container and extending above the open top and a movable plate or platform operable in the frame from a position closing the top of the container to one end of the open frame, said plate being free to move in the frame by the weight of a filled carton resting thereon when the device is lnverted whereby the said filled carton may be removed through the open top.

said frame from a position closing the said open top to one end of the open frame, said plate being free to move in the frame by the weight of a filled carton resting thereon when the device is inverted whereby the said filled carton may be removed through the open top.

5. A carton filling device of the class described comprising a container open at its top and bottom for receiving a carton in an inverted position, an open frame secured to the opposite sides ofthe container and extending above the open top, a plate or platform and an operating plunger connected thereto slidable in the frame and constituting a closure for the open top in one of its positions, means for guiding the sides of said plate or platform in the frame, said plate or platform being movable to one end of the frame in another of its positions whereby the filled carton may be removed throu h the frame as the container is invertei 6. A carton filling device 'of-the class described comprising a containerbpen at its top and bottom for receiving a carton in an inverted position, an open frame having parallel sides connected to the container and extending considerably above the top thereof, grooves formed in the parallel sides, a top connecting bar between the sides, a fiat plate or platform having an operating plunger extending through the connecting bar, an actuating handle for the plunger, means on the ends of the plate or platform operable in the grooves, said plate or plunger being movable to close the open top of the container in one position and constituting a support for a filled carton when-being removed in another position. 4

7. A carton filling device of the class described comprising a container open at its top and bottom having a frame extending above the open top and slidable means operable between the sides of the frame for ture.
